Sudden small patch hair growth on lower back of seven month old boy.

My daughter-in-law showed me a small patch(approx 4 or 5 hairs) that have suddenly appeared on the back of my grandson. It's in the lower right side. She said it has just appeared in the last few weeks but the hair seems to be growing rapidly. I understand that sudden hair growth in a small patch can sometimes be an indication of a serious condition(tumor, etc) Should she take him to the pediatrician for this condition. My worry is that it has occured so quickly. Any thought?
